Abstract: A reversible, disposable thermometer having an indicia of temperature spaced apart from a viewing window. A temperatureresponsive material which is not transparent in its solid state is disposed within bores distributed within the window. When in the solid state, the temperature-responsive material acts as a shutter to obscure a legible view of the indicia through the window. When the temperature of the thermometer is raised to the temperature represented by the indicia, the temperatureresponsive material melts and becomes transparent, thus rendering visible the indicia of temperature, while remaining held by capillary attraction within the bores. When the temperature of the thermometer decreases below the solidification point of the temperature-responsive material, the material remains in the bores and again becomes opaque or translucent, thereby permitting a re-use of the thermometer.
